amailloux Posted November 18, 2013 Share Posted November 18, 2013 Is it replaceable? Catalog shows 7 bulbs, but not which ones. Anyone know before I pull it out. Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted November 19, 2013 Share Posted November 19, 2013 I'm pretty sure that's a multi colored led. Green for engaged and orange for disengaged. Quote Link to comment Share on other sites More sharing options...
amailloux Posted November 19, 2013 Author Share Posted November 19, 2013 They passed on a 450 dollar cluster. Did go for a new solenoid pack for the trans though. Thanks. Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted November 19, 2013 Share Posted November 19, 2013 I may have been wrong on that year model, I can't remember now. I know the newer ones are led's. From the work shop manual: Q4 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION [*]Disconnect the instrument cluster connector. [*]Check for: [*]speed control bulb [*]corrosion [*]pushed-out pins [*]Connect the instrument cluster connector and make sure it seats correctly. [*]Operate the system and verify the concern is still present. Quote Link to comment Share on other sites More sharing options...
amailloux Posted November 19, 2013 Author Share Posted November 19, 2013 I read that exactly earlier, up to 2005, it may be possible, it not 06 to 10. Quote Link to comment Share on other sites More sharing options...
mchan68 Posted November 19, 2013 Share Posted November 19, 2013 They passed on a 450 dollar cluster. Did go for a new solenoid pack for the trans though. Thanks. I guess that means this truck is equipped with the 4.0L SOHC (which is backed by the 5R55S with the troublesome solenoid packs), as opposed to the 4.6L 3-valve (backed by the 6R60).

amailloux Posted November 19, 2013 Author Share Posted November 19, 2013 Yep. Had 0 rpm drop. I could command the solenoid, and hear it click also. I dropped the pack and used a short piece of hose and my lungs to determine it can not allow pressure. After hearing the solenoid click I thought a new converter or stuck valve was going to be at fault. Quote Link to comment Share on other sites More sharing options...
